Judge Blocks RFK Jr's Vaccine Policy Changes, Future Uncertain
A federal judge blocked Robert F. Kennedy Jr.'s major changes to federal vaccine recommendations, putting all his health policy moves since June 2025 on hold. The court pause came as measles cases surge across the country with 588 reported cases.

A federal judge has temporarily stopped Robert F. Kennedy Jr.'s sweeping overhaul of America's vaccine policies. The court order puts on hold everything the Trump administration has done to change vaccine guidance since June 2025.
Kennedy, who leads the Department of Health and Human Services, had made major changes to federal vaccine recommendations. Anti-vaccine activists have been working with committee members to eliminate vaccine requirements, focusing their efforts at the state level.
The legal pause comes as measles cases are climbing nationwide, with 588 cases reported so far. Health experts worry that uncertainty around vaccine policy is already causing damage, even if the changes get reversed later.
"The future of the US vaccines landscape depends on what the government does next," said Dorit Reiss, a vaccine law expert at University of California College of the Law, San Francisco.
The court will make a full ruling later on whether Kennedy's vaccine policy changes can move forward. For now, the old federal vaccine guidelines remain in place.
Your family's vaccine requirements for school and work could change depending on what happens next. The confusion around vaccine policy is already causing some parents to skip shots for their kids, which could lead to more disease outbreaks.
The court will issue a full ruling on Kennedy's vaccine policy changes. State-level vaccine mandate battles are expected to continue.
